"For a person as obsessed with music as I am, I always hear a song in the back of my head, all the time, and that usually is my own tune. I've done that all my life"

This quote by Bjork talks to her deep connection to music and how it has been a part of her life for as long as she can keep in mind. She is consumed with music and it is always playing in the back of her head, even when she is not actively listening to it. This is her own tune, something that she has been hearing all her life. It is a reminder of her enthusiasm for music and how it has actually belonged of her life for so long. It is a suggestion of the joy and convenience that music brings her and how it has actually been a continuous companion throughout her life. It is a reminder of the power of music and how it can bring people together and create a sense of unity and understanding.
